has anyone ever ran a 120 on the front

i think the stock mudguard would rub, but lf say like me u can have Katana mudguard *Which fits on the stock gs500 fe* u would have the clearance to run a 120

I have 120-60-17 front and 160-60-17 rear.Shinko oo5 Advanced.I tried it on the GS front before upgrading to a Katana750 front end.It worked.How ever the GS fender is a little tight.A good replacement,looks better also,is an 88-97 Katana 600/750 front fender or 1st gen Bandit 400/600.No mods are needed.I am currently running a Bandit 400 front fender.

I've got Sportec M-1 120/70 on the way.  It would be a bit narrower but slightly taller than a 120/60 right? Would this clear the GS fender?

Thanks.

Theoretically,

A 110/70 tire is 110 x 70% = 77 mm tall
A 110/80 tire is 110 x 80% = 88 mm tall
A 120/70 tire is 120 x 70% = 84 mm tall
A 120/60 tire is 120 x 60% = 72 mm tall

A 120 mm tire on a 3.00" rim is 115 mm wide, preferred rim is 3.50"
A 110 mm tire on a 3.00" rim is 115 mm wide, preferred rim is 2.50"

So theoretically a 110/80 is same width and a little taller than the 120/70 when mounted on the 3.00" GS front rim.  Actual dimensions vary a little for different makes and models of tires. 

First 110/80 I put on my 97 GS rubbed the acorn nuts on the 2 screws that held the mudguard on the fender.  I turned the screws around putting their flat button heads on the inside and the acorn nuts on the outside and had no further problems with 110/80 tires on the 97.  My 02 GS doesn't have the mudguard and has clearance for the 110/80 tires I've run.

I prefer the 110/80 tires to the 120/70/65/60 tires on the GS, makes the speedo more accurate.     But the 120's should fit mounted on the GS 3.00" rim.  Don't forget a tire is 5 mm or .2" wider or narrower when mounted on a rim that is 1/2" wider or narrower than the preferred or measuring rim specified by the tires maker.

You've obviously done your research   Really appreciate the info and am now feeling pretty sure it'll fit.

THanks.
